python 必知必会:

• https://pypi.org/

pkg_resources

• https://setuptools.pypa.io/en/latest/pkg_resources.html
• https://stackoverflow.com/questions/7446187/no-module-named-pkg-resources
• 是 setuptools 内的模块, 用于处理目录解析等, 非常方便.
• 已经废弃!! 替代品:
  • importlib.resources
  • importlib.metadata

poetry add --dev setuptools


poetry run pip install setuptools



pip install setuptools


pip install --upgrade setuptools
pip install --upgrade distribute

python import local module/library:

• https://fortierq.github.io/python-import/

fix 1:

• ✅️ 简单粗暴的插入路径!

from pathlib import Path
import sys
path_root = Path(__file__).parents[2]
sys.path.append(str(path_root))
print(sys.path)
                
import src.c.d

fix 2:

• ✅️ 传入 -m xxx-module, 显式指定 -m 一个本地模块.

~/Documents/code/project$ python3 -m src.a.b  # note that we use . and not / here

Name: __main__
Package: src.a

fix:

export PYTHONPATH=/home/user/my_libs
python myscript.py



import sys
sys.path.insert(0, '')
